Product Analysis

1 At the request of the purchaser, an analysis of two pipes from each lot shall be made by the manufacturer.

2 The results of these analyses shall be reported to the purchaser or the purchaser’s representative, and shall conform to the requirements

3 For grade P 91 the carbon content may vary for the product analysis by −0.01 % and +0.02 % from the specified range

4 If the analysis of one of the tests specified in 8.1 does not conform to the requirements specified in 6.1, an analysis of each billet or pipe from the same heat or lot may be made, and all billets or pipe conforming to the requirements shall be accepted.
